Question

Express 35 mm in cm, m, and km

Answer 1

Step 1: Express $mm$ into $cm$

We have, $35mm$

We know that, $1cm=10mm$

Now solving to get the value of $35mm$ in $cm$

$$\begin{gathered} \Rightarrow 1mm=\frac{1}{10}cm \\ \Rightarrow 35mm=\frac{35}{10}cm \\ \Rightarrow 35mm=3.5cm \end{gathered}$$

Step 2: Express in millimeter in meter

We know, $1m=100cm$

Now solving for $35mm$

$$\begin{gathered} \Rightarrow 1cm=\frac{1}{100}m \\ \Rightarrow 3.5cm=\frac{3.5}{100}m \\ \Rightarrow 3.5cm=0.035m \\ \Rightarrow 35mm=0.035m \end{gathered}$$

Step 3: Express meter in kilometer

We know that, $1km=1000m$

$$\begin{gathered} \Rightarrow 1m=\frac{1}{1000}km \\ \Rightarrow 0.035m=\frac{0.035}{1000}km \\ \Rightarrow 35mm=0.000035km \end{gathered}$$

Hence,$35mm$ expressed $cm,m$and $km$is given as

$$\begin{gathered} 35mm=3.5cm \\ 35mm=0.035m \\ 35mm=0.000035km \end{gathered}$$
